The shipbuilding and offshore plant industry of Korea is important and leads Korea's economic growth, designated as the 1st to 4th export items in Korea in terms of export contribution over the period from 2011 to 2015. This study proposes ways to improve the national competitiveness of Korean shipyards in the global offshore drilling market by reviewing a business model for providing an integrated offshore drilling commissioning service in Korea. This commissioning service model, which was attempted in 2014, was reviewed, and a new proposed business model for overcoming the limitations of the previous model and activating further business was evaluated. As a result of an economic evaluation, it was found that a 150-meter water depth model is economically more effective. As the number of integrated commissions increased from 2 to 5 times per year, NPV, IRR and B/C ratios increased and the fee per use decreased. Therefore, for offshore drilling facilities constructed and delivered in Korea, it will be necessary to encourage integrated offshore commissioning.

Offshore drilling refers to a mechanical process where a wellbore is drilled through a seabed. It is typically carried out in order to explore for and subsequently extract petroleum which lies in rock formations beneath the seabed. There are many different type of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs, combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units including semi-submersibles and drillships. These are capable of operating in water depths up to 3,000 m. In this paper, we introduce the drilling system, which is mounted on the offshore drilling facilities.

Because offshore plant industry needs to design, deploy and operate much of equipment especially, the latest trend shows the installation of production facilities is augmented in the subsea. The installed facilities are very difficult to be repaired or changed because they are located in the subsea. For solving these problems, both the directly related information of the production like the optimal number, position and depth of wells and the distribution for effective operation and safety of equipment of subsea should be considered at the preliminary stage of FEED (Front End Engineering Design). The marine exploration is introduced in this paper for providing the fundamental technology to answer the questions related to above considering points. First, some kinds of the offshore plant facilities are enumerated and aims of marine exploration for the offshore oil/gas development are summarized. In addition to it, the main roles of marine survey, in the step of designing and installing offshore oil-gas plant, development are briefly listed. And then foreign examples are shown to help the reader's understand. This paper is hoped to be helpful for understanding the marine exploration that can be applied to offshore oil/gas plant and to be contributed to developing the domestic techniques in this field for the future.

극지개발을 위해서는 극지의 혹독한 자연환경을 대상으로 하는 과학지식과 극지에서 사용되는 특수시설과 장비를 설계, 시공 그리고 운용하는 공학기술이 요구된다. 극지관련 공학기술은 저 온용재료 관련기술, 도로나 교량, 건축물과 같은 극한지 천연자원의 시추와 생산, 수송을 위한 해양구조물과 파이프라인 관련기술, 그리고 얼음의 재료특성에 관한 이론 및 실험으로 크게 구 분할 수 있다. (Table 1). 극지용 구조물과 빙해항행선박 (쇄빙선) 은 일반 해역에서 운용되는 구조물에 비해 형상, 구조강도, 의장, 저온특수설비 등에서 새로운 개념의 기술이 요구되기 때 문에 금후 국내 조선해양산업계가 지향해야 할 고도의 기술집약형 건조물이다. 또한 최근 들어 국내에서도 시베리아 천연자원의 해상운송을 위해 빙해역을 운항할 수 있는 유조선이나 일반 화물선을 확보해야할 필요성이 대두되고 있으며, 또한 국내 조선업계의 생산기술이 비약적으로 발전함에 따라 외국으로부터의 빙해항행선박의 수주도 이루어지고 있으나 아직 이들 선박의 설계를 위한 독자적인 기술은 미흡한 현실이다. 극지개발은 이론적 접근과 함께 실험에 의한 신뢰성 있는 자료를 축적해야 한다. 이를 위해서는 빙해수조(,ice model basin)의 건조나 빙역학 실험을 위한 냉동실험실 (cold room)의 건립을 위한 초기투자가 절실히 요구되며 산업계의 수 요에 따른 포괄적인 산학협동연구가 진행되어야 할 필요가 있다. 빙해수조와 냉동실험실은 빙 해역에 직접 접하지 않은 국가에서 극지공학 연구에 참여하기 위한 필수적인 시설인데 table 2에 대표적인 빙해수조의 설치장소와 규모에 대하여 정리하였다. 이 글은 우리 나라가 쉽게 접할 수 없는 극지환경을 이해하고 가까운 장래에 예상되는 수주경쟁에 대비하여, 국내외의 극지개발 동향을 분석하고 이에 대한 국내의 극지관련 연구의 현황과 앞으로의 전망을 살펴보기 위하여 준비된 것이다. 이 글에서는 극지공학 일반보다는 조선해양분야에 관련된 내용만으로 국한한다.

Today, it is a trend that the demand of offshore plants is constantly growing, along with the advances in technology which are thoroughly needed to the rise of international oil price as well as offshore energy development. In addition, The main sectors of ship building, sale & purchase and chartering market regarding various kind of offshore supporting vessels that supports the business of offshore energy development is now maintaining its steady growth. However, in domestic case, the contract of time charter occasions regarding the offshore support vessel are almost non-existing situation. Thus, the relevant practical study regarding to implementation of various kinds of legal disputes and applicable laws that can be properly applied in time charter and the field of sale & purchase needs to be conducted actively. Therefore, the concept of this study has included the wide comparisons of other special provisions with the existing time-charter by making its base on "Supply Time 2005" which is the worldwide standard form of time charter in offshore support vessel market and its investigation, aiming to provide practical guidance and procedure for implementation of arbitration and applicable law issues which can be applied in legal disputes between parties.
